My car seems to be struggling to maintain fuel pressure. At idle and engine off, I get a steady 3bar (43psi) If I prod the throttle, I get dips in fuel presure down to 35psi I'm going to change the filter first, and maybe the regulator but from experience, the last time I had this problem, it was the fuel pump. Caterham parts are out of stock and seem to only list the pump with the whole assembly with the bits that attacj=h it to the tank. They want £300 for this. http://caterhamparts.co.uk/product.php?id_product=98 Would this do the job? - At <£100, and without all the extra bits I don't need, it looks much more temptimg https://www.merlinmotorsport.co.uk/p/fuel-pump-caterham-injection-motorsport-ac-6443327-itp144?utm_source=Google&utm_medium=ShoppingUK&utm_campaign=ShoppingUK&vat=on¤cy=GBP&gclid=CjwKEAjw-8ihBRD2t9qT3NaW7igSJAD3_sNV2pzl33x_rUk6mRUc4QldIR0OXf_Ni1tQLS-OmySppBoC21nw_wcB From memory, when I last changed the fuel pump, it was listed as a "high pressure injection pump" rather than a standard in tank pump. Is there anywhere else that I can source a suitable pump from? The engines a Swindon JPE Vauxhall engine. Thanks
